A three-dimensional object manufacturing method includes a molding step of molding a first three-dimensional object, a second three-dimensional object and a first support part for coupling the first and second three-dimensional objects at mutually different positions on a base plate by an additive manufacturing, and a separation step of separating the first three-dimensional object, the second three-dimensional object, the first support part and the base plate from each other. In the separation step, the first and second three-dimensional objects are separated from each other by dividing the first support part after at least one of the first and second three-dimensional objects is separated from the base plate.

Methods and systems for fabricating a component by consolidating a first portion of a particulate include a louvered particulate containment wall positioned around the component and a second portion of the particulate. At least one louver is coupled to the particulate containment wall adjacent at least one opening in the particulate containment wall. The particulate containment wall is positionable between a first position in which the louver prevents the second portion of the particulate from flowing through the passage and a second position in which the second portion of the particulate is able to flow through the passage. The methods include switching the particulate containment wall from the first position to the second position and allowing the second portion of the particulate to flow out of the interior space through the at least one opening.

A supported product manufactured using additive manufacturing, wherein the supported product provides a simplified post processing. The supported product contains a product and a support structure, wherein the supported product has been manufactured using additive manufacturing as a whole, wherein the support structure is adapted to be removed to provide the product, wherein the support structure provides an interface adapted to interact with a counterpart of a tool for removing the support structure.

According to an example, a device comprises a sidewall and a base. The sidewall and the base define a chamber for receipt of a volume of build material comprising loose build material and a solid object generated from the build material in an additive manufacturing process. The base is not permeable to build material but permeable to a gas to allow an influx of a gas into the chamber to fluidize loose build material around the solid object in the volume of build material in the chamber to facilitate the removal of the solid object from the loose build material.

The present disclosure provides three-dimensional (3D) objects, 3D printing processes, as well as methods, apparatuses and systems for the production of a 3D object. Methods, apparatuses and systems of the present disclosure may reduce or eliminate the need for auxiliary supports. The present disclosure provides three dimensional (3D) objects printed utilizing the printing processes, methods, apparatuses and systems described herein.

According to one example there is provided a non-transitory computer readable storage medium comprising instructions that, when executed by a processor, cause the processor to: obtain an object model; analyse the object model; obtain characteristics of an interface agent; generate a modified object model comprising a support structure and an interface between the support structure and the object, the interface being such that after generation of a 3D printed green part and after sintering thereof, the support structure may be released with a predetermined force; and controlling a 3D printer to generate a 3D printed green part based on the modified object model.

In one aspect, an additive manufacturing system is provided. The additive manufacturing system includes a build platform, a first plurality of particles positioned on the build platform, and a particle containment system positioned on the build platform. The particle containment system includes a particle containment wall. The particle containment wall at least partially surrounds the first plurality of particles and includes a second plurality of particles consolidated together. The particle containment wall includes a top end spaced apart from the build platform, an inner face positioned against the first plurality of particles and extending between the build platform and the top end, and an outer face that faces a substantially particle-free region, the outer face positioned opposite the inner face and extending between the build platform and the top end.

A system and method are disclosed for additively manufacturing an object having an internal chase. The system and method include evaluating a print design file that defines physical properties of the object to be printed with the additive manufacturing process to determine whether the object can be printed with a removable plug located inside the internal chase, and if so, modifying the print design file to include the removable plug. The object is then printed with the removable plug, which is removed prior to removing the support material.
